Description
The present invention relates to a lighting device for a refrigerator for refrigeration and freezing.
The lighting fluorescent lamp provided in the refrigerator for cold storage and freezing reduces the illuminance or flickers the fluorescent lamp due to the cooling of the low-temperature air in the refrigerator.
Means for preventing the decrease in the illuminance of the fluorescent lamp are: or boosting the pressure by using a dimming device, or covering the fluorescent lamp by using a cover tube so as not to be cooled by low-temperature air.
When the fluorescent lamp is covered with the cover tube, the fluorescent lamp having a diameter larger to some extent can be prevented from being cooled, but the temperature range of the display goods in the refrigerator to be cooled is different depending on the kind of the display goods.
Therefore, when the fluorescent lamp is covered with one cover tube for illumination, the fluorescent lamp can be prevented from being cooled only in this temperature region.
The invention can prevent the fluorescent lamp from being cooled in 3 temperature areas by installing two cover tubes.
The lighting device for a cooling refrigerator according to claim 1 includes: a1 st cylindrical portion for a socket is provided on one side of an end plate, an end portion of a fluorescent lamp is inserted into the socket, and a 2 nd cylindrical portion concentric with the 1 st cylindrical portion and forming an annular gap with an outer circumferential surface of the 1 st cylindrical portion is provided on the end plate. The end of the 1 st cover pipe can be inserted into the gap, and the end of the 2 nd cover pipe can be embedded on the periphery of the 2 nd cylinder part.
Further, the refrigerator according to claim 2 of the present invention includes the following lighting device; the lighting device has a pair of left and right sockets arranged in the refrigerator, the socket is provided with a 1 st cylinder part inserted with the socket of the end part of the fluorescent lamp on an end plate, and a 2 nd cylinder part concentric with the 1 st cylinder part and forming a gap for inserting the cover pipe with the outer periphery of the 1 st cylinder part is formed on the end plate; inserting the end part of the fluorescent lamp into the 1 st cylinder part, and holding the fluorescent lamp by the left and right 1 st cylinder parts; further, either one or both end portions of the cover pipe are fitted to either one of the outer sides of the left and right 1 st tubular portions or the outer side of the 2 nd tubular portion, or both the 1 st tubular portion and the 2 nd tubular portion.
An embodiment of the present invention is illustrated below in the figures. Wherein,
fig. 1 is a longitudinal sectional view of an example of a refrigerator having a lighting device according to the present invention.
FIG. 2 is a longitudinal sectional view of the lighting device of the present invention.
Fig. 3 is a longitudinal sectional view of the lighting device of the present invention.
The symbols in the figures represent: 1-refrigerator main body, 11-socket, 12-end plate, 13 a-1 st cylinder, 13 b-2 nd cylinder, 14-gap, 15 a-1 st cover tube, 15 b-2 nd cover tube, 16-fluorescent lamp, 17-hole, 18-connecting terminal, 19-cover, 20-lead wire, 21-lamp holder.
Fig. 1 shows an example of a refrigerator lighting device of the present invention and a vertical type switch refrigerator having the lighting device.
In the vertical opening and closing refrigerator shown in fig. 1, an air curtain formed by cooling air blown out from an upper air outlet is formed at a commodity doorway 2 opened in the front of a refrigerator main body 1. The air of the air curtain is sucked into the air passage through the lower suction port 4; after passing through a blower and a cooler 6; and is blown out again from the blow-out port as cooling air.
The refrigerator is provided with a fluorescent lighting device 8 for lighting commodities on a display shelf 7. The present invention relates to improvements in such devices.
The present invention improves the socket structure of the lighting device and the new structure will be explained below.
The socket 11 is provided with a hole 17 for inserting an end cap terminal pin 16a of a rod-like fluorescent lamp 16, and a short 1 st cylindrical portion 13a of the socket for inserting an end portion of the fluorescent lamp 16 is provided on a reverse side (opposite side of a pair of sockets) of the end plate 12 having a terminal 18 on one side (outer side), and a short 2 nd cylindrical portion 13b concentric with the outer peripheral surface of the 1 st cylindrical portion to form a gap 14, and an end portion of a transparent 1 st cover tube 15a is inserted into the gap 14, and a transparent 2 nd cover tube 15b is fitted into the 2 nd cylindrical portion 13 b.
Further, the 1 st tubular portion 13a is extended by a length L as compared with the 2 nd tubular portion 13b so as to be extended more than the 2 nd tubular portion 13b, and when the 1 st cover pipe 15a is inserted into the gap 14, the extended portion of the 1 st tubular portion 13a is guided so as to be easily inserted thereinto.
Reference numeral 19 denotes a socket cover, and the socket is integrally formed by a cover, an end plate, and 1 st and 2 nd cylindrical portions.
The reference numeral 20 denotes a lead wire to a terminal, and 21 denotes a lamp holder, which is made of a plastic or metal material having a suitable elasticity, and is capable of clamping either one of the 1 st and 2 nd cover tubes 15a and 15 b.
The use method of the lighting device comprises the following steps:
(a) case where only the small-diameter cover tube 15a is used:
in this case, the end of the cover tube 15a is inserted into the socket gap 14 and fitted outside the 1 st cylindrical portion 13 a.
The use case is suitable for occasions where the temperature area in the cold frame is not low, such as refrigeration of vegetables, fruits and the like.
(b) Case where only the large-diameter cover tube 15b is used:
in this case, the end of the cover tube 15b is fitted to the outside of the socket 2 nd cylindrical portion 13 a.
The use case is suitable for the low temperature area in a refrigerator, such as refrigerating raw fish, fresh fish meat and the like.
(c) The case where the small-diameter cover tube 15a and the large-diameter cover tube 15b are used together:
in this case, the end of the cover tube 15a is fitted into the socket gap 14 and fitted outside the 1 st cylindrical part 13; the end of the cover tube 15b is fitted to the outside of the socket 2 nd cylindrical portion 13 a.
This use case is suitable for the case where the temperature region in the cold frame is low and is used for freezing, such as freezing of frozen food.
According to the lighting device of the present invention, the cover tube can be used corresponding to 3 different temperature regions as in the above 3 cases.
This prevents the fluorescent lamp from being overcooled by the cooling air, thereby preventing the illuminance of the fluorescent lamp from being lowered.
Since the reduction of the illuminance due to cooling can be prevented, a light control device such as a regulator is not required, and a fluorescent lamp with high illuminance is not required, thereby achieving the energy saving effect.
The illuminance ratios when the large and small masks were used separately and together (the experimental results when the illuminance of the 1 st mask was 100 were as follows:
< illumination test conditions >
Wattage of fluorescent lamp: 40W
Outer diameter of No. 1 shroud: 38mm
Outer diameter of 2 nd shroud: 42mm
Temperature: 0 deg.C
< illuminance results >
Using a cover tube: ratio of illuminance
1, covering the pipe: 100
A 2 nd cover pipe: 120
The two are used together: 132
The illuminance test results are as shown above, but according to the present invention, the life of the fluorescent lamp can be extended.
The present invention is applicable to a vertical open/close refrigerator in which a commodity entrance is opened at the front, a horizontal refrigerator in which a commodity entrance is opened at the top, and a refrigerator having a sliding door different from the open/close door.
The invention solves the problem of anti-cooling of fluorescent lamps corresponding to 3 temperature areas by two cover pipes, can prevent the reduction of illumination intensity, does not need a dimming device, can reduce the cost of a lighting device in a refrigerator, and has the advantage of energy saving.
